This utility model discloses a wall-scraping stirring device for solid-liquid extraction, including a stirring tank. A driving mechanism is mounted on the upper surface of the stirring tank, and a stirring shaft connected to the driving mechanism is rotatably mounted inside the tank. Several sets of main stirring blades are evenly arranged on the stirring shaft. A groove is formed on the side surface of each main stirring blade, and a T-shaped movable plate is slidably mounted within the groove. A scraper is mounted on the side surface of the movable plate, contacting the inner wall of the stirring tank. By setting the movable plate and scraper on the main stirring blades, the hard deposit layer formed on the inner wall of the stirring tank is scraped away while stirring, preventing deposit scaling and maintaining an effective mass transfer area. The staggered arrangement of the main stirring blades generates an axial-radial composite flow, eliminating low-speed dead zones. While scraping the wall, the scraper rapidly pushes the high-concentration slurry on the wall surface to the mainstream zone, disrupting the boundary layer concentration gradient and preventing emulsification caused by local concentration gradient imbalance, thus improving the rare earth recovery rate.
